Abstract
Official abstract text for this publication.
An RF front-end module includes power amplifiers, transmission-side filters, a reception-side filter, and a switch IC. A first transmission signal is output from a first transmission signal input terminal to a first common terminal via the power amplifier and the transmission-side filter. A second transmission signal is output from a second transmission signal input terminal to a second common terminal via the power amplifier and the transmission-side filter. A first reception signal input from the first common terminal and a second reception signal input from the second common terminal are input via the switch IC to the reception-side filter, common to the first and second reception signals, and are output from the reception-side filter to a reception signal output terminal.
